# minidemo

#### 介绍
该仓中的文件是minidisplay demo的gn配置文件
This is a porting re-engraving experiment code warehouse. The name of product has been changed to minidemo.
#### 使用说明

1.  获取[OpenHarmony](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/get-code/%E6%BA%90%E7%A0%81%E8%8E%B7%E5%8F%96.md)完整仓代码。
2.  参考[快速入门](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/Readme-CN.md)搭建环境。
3.  cd进入vendor/huawei目录，git clone https://gitee.com/grecozf/minidemo.git 。
4.  cd进入device目录，git clone https://gitee.com/grecozf/minidemo_st.git 。
5.  下载arm交叉编译器，git clone https://gitee.com/harylee/gcc-arm-none-eabi-10-2020-q4-major.git ，将交叉编译器环境变量bin目录配置到.bashrc文件中或者配置device/st/stm32l4r9i_disco/liteos_m/config.gni文件中board_toolchain_path宏为交叉编译器bin路径。。
6. 编译
```
grecozf@grecozf~VirtualBox:~/OpenHarmony$ hb set
[OHOS INFO] Input code path:
OHOS Which product do you need?  minidisplay_demo@huawei
grecozf@grecozf~VirtualBox:~/OpenHarmony$ hb build
```
7.  最终的镜像生成在out/stm32l4r9i_disco/minidemo/目录中，通过STM32 ST-LINK Utility软件将DISCO_L4R9I.hex下载至单板即可。
